Rodrigo Siqueira fb7c68bbcc drm/amd/display: Add minimal pipe split transition state 
commit 97ca308925 upstream.

[WHY?]
When adding/removing a plane to some configurations, unsupported pipe
programming can occur when moving to a new plane.  Such cases include pipe
split on multi-display, with MPO, and/or ODM.

[HOW?]
Add a safe transistion state that minimizes pipe usage before programming
new configuration. When adding a plane, the current state has the least
pipes required so it is applied without splitting.  This must be applied
prior to updating the plane_state for seamless transition.  When removing a
plane, the new state has the least pieps required so it is applied without
splitting.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
